[2022] Bots and how to fight them?

Bots are big topic of conversation right now in Lost Ark. Yes I know Lost Ark is f2p and AoC will be sub based...

However, this alone may not prevent bots. Gold sellers and bots have been a part of MMO's since WoW classic, maybe before...

I have been sold on the idea of using a mobile phone number for account creation, along with an email. This would prevent bots and have the added benefit of automatically enrolling a user into MFA (account hacking is also still common in the genre).

Curious on everyone's thoughts on this?
